Duties In January 1992, the citizens of Allen passed a citywide half-cent sales tax in support of an economic development corporation. Since its inception, the AEDC has been charged with facilitating expansions and relocations of new and existing businesses that in turn will bring additional tax revenue, local spending and job opportunities to the community. A five-member board of directors, appointed by the City Council, oversees the corporation’s operations. Contact Executive Director Dan Bowman at 972.727.0250 for more information.
